My husband has decided that we need to go to Yellowstone this year for vacation. We have three children ages 11, 9 and 2. We will be on a budget and love corny, unusual places to see and things to do that cost little to nothing. Unusual places to stay too. (Although we have a pug that MAY go along with us). I have mapped out our trip to include a stop in St. Louis, Omaha and Sioux City. We plan to visit the Badlands, Blackhills, Mt. Rushmore, Yellowstone and whatever else we can find along the way.
I guess my question is what are some budget friendly sites and places to stay and what type of money are we talking about for a trip like this.
